10.Attach the cable collector insert to the cable collector cover using the 2 Phillip screws provided.

11.Place the control head back onto the mounting bracket. Plug in the cable collector assembly to the back of the control head. Cable connectors and cable sockets are keyed to prevent reverse installation, so be careful not to force the connectors into the wrong sockets. Once the cable collector and all cables are plugged into the back of the control head, lock the assembly into place by threading the knurled screw into the threaded insert on the back of the housing. Adjust the control head to the desired viewing angle and secure by tightening the gimbal knobs.

NOTE: You may wish to dress the cabling with nylon wire ties in order to hold the cables together and create a cleaner assembly.
